Better Water Resources Management: (Part 3)
Coastal Hydrogeology With Mathemathical Modeling
Due to rapid urban development, climate change, intense agriculture and other factors shallow unconfined aquifers in a lot of coastal regions have become highly vulnerable to contamination from sea water intrusions.
The SEAWAT program is designed to simulate variable-density ground-water flow and solute transport in three dimensions. The underlying concept of SEAWAT is to combine an existing flow code (MODFLOW) with an existing solute-transport code (MT3DMS) to form a single program that solves the coupled flow and solute-transport equations.
One benefit of the SEAWAT approach is that improved and updated versions of the flow and transport codes can be incorporated into the SEAWAT program to take advantage of recent improvements. Another benefit is that users familiar with the constant-density versions of the flow and transport codes can easily apply the SEAWAT program to variable-density ground-water problems.
- Set up 3D conceptual model in MODFLOW with 11 layers
- Assign both MODFLOW and SEAWAT boundaries (for seawater intrusion model)
- Properly set up different parameters in SEAWAT
- Run the transient SEAWAT seawater intrusion model
- Visualize results in 3D
- Learn which groundwater sampling method works the best in coastal zones influenced by seawater intrusion?
- Learn what are typical groundwater discharge rates in coastal zones around The World - compare it with your model to validate it.
- Analyzing local and regional SEAWAT model for water resources management - case study from USGS (United States Geological Survey)
Who should attend?
This course is ideally suited for hydrogeologists,
environmental engineers and climate change experts as an additional skill to make informed decisions in coastal zones.
B.Sc in hydrogeology, geology, environmental engineering, civil engineering.
Average 2 - 3 hours per week to finish course. We encourage you to spend time with the course each week. Your focused attention will pay off in the end!
If anything seems unclear or you just have a question, then please let me know - I will get back to you as soon as possible, usually less then 24 hours. After each lecture you have place to ask questions. Again, thank you for joining me on this course.

More than 20 years in the field of water and environment, specialist in quantitative hydrogeology applying his knowledge on projects in Europe, US, Middle East, Australia and Africa. Uncertainty analysis of groundwater models is his another specialization. One of top success was mentoring one of the top world Australian Mining Company in using specialized techniques of mathematical model calibration and uncertainty analysis with PEST.
His Ph.D. was done on the topic of groundwater remediation. On the Middle East he was working on a capital project for the metro. A huge database was established (more than 500 observation points).
Business Development and Marketing
Working from Serbia he manages to set up brand acknowledged on Geological Survey of US Meeting in US 2019 as an example of how brand can be setup from distant country. The first online Conference Groundwater Science and Practice was organized in 2018. Proud to say that he become one of the moderators of the LinkedIn Groundwater Modeling Forum with 7000 members along with several university professors. He raised 100000 USD for his Start-Up. Another Start-Up is currently under development.
Coaching other companies and their engineers
First started with 1 on 1 courses throughout the world (mostly US) conducting Environmental Science Education Program with 900 participants.Topics were Water Resources Management, Remote Sensing and Seawater Intrusion. He was accepted on The John's Hopkins University for online specialization in 2018 where he attended one semester of Air Resources Monitoring and Management. Due to catastrophic air pollution in his native country he stopped his specialization on JHU and devoted his time to mitigation of indoor pollution with a top company in that arena. He was again accepted to continue his specialization in JHU in 2020. As one of greatest achievement was invitation to train JHU Ph.D. student in interpretation of Mars geology. Due to COVID-19, the project was postponed by NASA. Also, at beginning of 2020 he was elected to be a reviewer of The Book Coastal Hydrogeology for US journal.
During his consulting practices he was working with Roscoe Moss and arena of Aquifer Storage and Recovery for several years.
He published over 20 scientific papers in his native language and the first one in English at MODFLOW Conference 1998. He published a book about Mathematical Modeling and Remediation that is currently under translation in English.
Sensors in Natural Resources
First started as his hobby after which his passion for electronics in environmental field was expanded and currently, he is writing a book on sensors application in natural resources.
By lunching of the Sentinel 2 satellite in 2016 he become interested in remote sensing and its application in water resources and agriculture. Did numerous projects in Agriculture and for big agriculture companies, the largest 10000 ha)
His integrated knowledge of different disciplines in environment enabled him to develop a specific approach to managing natural resources (monitoring, modeling and remote sensing) Developing techniques for the determination of mineral resources from satellites was considered by several companies.

What our Clients Say About Us
Dragan is a fantastic technical resource. With his assistance, I’ve
been able to greatly improve my groundwater modeling and GIS skills. I
will continue to seek him out for my professional development needs. He
provided great value and was a pleasure to work with!
- Bob Marley - Senior Hydrogeologist at EA Engineering, Science, and Technology, Inc., PBC
I have known Dragan for many years. I am most impressed with his dedication to hard work, and the breadth of his knowledge on environmental data acquisition and processing, software, and modelling.
- John Doherty Owner, Watermark Numerical Computing, Australia
He is always available for questions and truly goes above and beyond in his training classes. I have gained a lot of knowledge over a short period of time working with Dragan and would highly recommend his services to others.”
- Thomas Ballard, PG, CHG, Consulting Hydrogeologist, USA
I took multiple training courses with Dragan. I learned a great deal with him during each of the courses. He is an excellent teacher willing to help out in any way possible.
- Mark Sherrill, Environmental Scientist at Short Elliott Hendricson, USA
"I recently completed a course in Remote Sensing and QGIS with Dragan. He was very knowledgeable and guided me through the theory and background and also the implementation of remote sensing. He was very personable and happy to answer all my questions. I appreciate having him as a reference and would recommend him to anyone interested in this topic."
